STUDDING.

Application filed November 30, 1923. Serial No. 677,669. l

To all whom t may concern.'

Be it known that I, CoRNELiUsCoLLINs, a citizen of the United States, and resident of Los Angeles, in the county of` Los Angeles State of California, have invented new and useful Improvements in Shielding, of, which the followingis a'specification. y

This invention relates to a studding for walls, partitions and like building elements. Therprimary object of this invention is to provide a stud which has strength both when under'tension and compression, is light :in

weight, incombustible,rigid, and economi-V cal. Itis another object of this invention. to provide a studding "of the character described which will permit nailing of parts thereto. y f

In addition to the objects above .enumerated, there are otherV objects which will be apparent from the subjoined.specification and drawing, in which:

Fig. 1 .isra perspective ,view of a hollow partition employing my improved studding ;V

Fig. 2 is a transverse section throughthe partition illustrated in Fig. .1 showing one of the studs in elevation; Fig. 3 is an elevation of a stud employing one channel as the skeleton; Figs. t t`o-7 inclusive .show studs with portions of the cementitious material broken away showing different types of foundations;4 and Fig. 8 is a perspective view of a stud. having only the end connections.-

Broadly the studcomprises a foundation or skeleton member and lath securing members formed of metalembedded in a cementi tious body. Referring more particularly to Figs. 1 and 2, floor slabs are indicated by 10 and v11. Suspended from the Vsla-b 10v is a ceiling 12 composed of a metal lath with a plaster finish. Secured on the under side of the ceiling at the plane of the partition is a plate 13. This plate is preferably a metal l channel and may be secured to the ceiling in any approved mamier.

In registration with the channel 13 and secured to the slab 11 is a plate l14. The studs are indicated generally by 15 in Fig. 1, and consists of cementitious bodies having skeletons formed of metallic plates extending beyond the body at the ends thereof to provide fingers for grasping the plates 13 and v111. Extendingv from the body are prongs to hold the metal lath in place.

Cross braces 16 are disposed between thc studs. Awooden stud 17 for a door frame 1s nailed to'one of the studs,.an overhead plate being indicated by 18. Disposed on the upper side of plate 18 is a plate 19.l

Referring more particularly to the. details of the stud, best` shown in Fig. 6, the skele-` tonconsists of metal channels 20 and 2l.

spaced-by clips 22. Y T urnedoutwardly from the channels are prongs 23. In the present instance, they are shown as cut from the body of the channel and upset therefrom'` The skeleton 1s embedded in a cementitious .body 24 formed of plaster or any suitable material, and, if surface reinforcement is desired, thenA a paper covering may be ap-v plied to the body in the manner ofvplaster board. As shown herein, the stud is a beam or column rectangular in cross section with prongs 23 projecting beyond'the body and the channels 20 and 21 extending beyond the end of the body to form fingers. Y There may beembedded in thestud, bars 25 as particiilarlyl shown in Figs. 1 and 2. These bars are such as to be received with the chan nels of the cross braces 16 shown in Fig. 1. The bars and cross braces may be secured together by rivets, bolts, or likefastening 'dc` vices. -It will be noted that the bars are of such width that they pass freely between the channels 20 and 21. In placing a stud in pos1tion,v openings are forme through the plastic body'in the ceiling, the meshes of the metal lath being opened vsufficiently. These openings are formed on the sides of the plate 13 so as to permit the fingers 2li' against the lath so as to firmly hold the latter in position, the whole constituting a unitary structure. The plaster is then placed over the lath and the wall finished in the usual manner. the top ofthe door frame serves for the fingers of short studs placed between the ceiling and the top of the door frame.

The plate 19 in Fig. 1 upon i Heretofore a very satisfactory partition construction has employed meta-l Vchannels provided with prongs, such as those forming the skeleton of the present stud. Metal lath has been secured to the stud and the samecovered with plaster in the usual inanner. IThe plaster has protruded through the meshes of the lath to the rear side forming a substantial thickness of plaster on the rear side of the metal lath. This has provided material to strengthen the partition. Metal lath is now on the market, which lath has secured thereto on the rear face a backing of paper. Thus, the plaster applied tothe face of the lath will intrude between the meshes but will not protrudey on the oppositek side thereof. lVith such a construction, the amount of plaster is Isuch as to lend little reinforcement, resulting in the necessity of a more rigid stud. My present stud employsthis metal channel as a skele-V ton and a cementitious body, lsuch as plaster. This provides a rigid, light, fire resistant stud having all the advantages of the metal stud. Futherinore, members can be nailed to the stud, 'such as base boards, chair rails, and the like, it not being necesl sary to providenailing blocks.

The plaster body may be easily broken away to permit the passage of bars or to eX- pose the skeleton for any purpose desired.

Referring particularly to Fig. 4, channels,

30 and 3l are secured together by separators 32. These separators are independent elements and are provided at the ends with bifurcations forming pairs of .lingers serving as prongs. The 'skeleton is covered by Y the ceinentitious body forminga column or cured thereto.

stud similar to the form shown in Fig. 6. Fig. 5 is similar to Fig. 4 in construction, except that a single channel bar 33 is employed for the skeleton, clips 34 being fse- The ends of clips 34 have prong fingers-'similar to the separators 32 of Fig. 4. The skeleton is covered with a cementitious body. Fig. 7 is a structure similar to Fig. 6, but having a 'single channel 35 with prongs 36 upset from the body thereof. The skeleton is covered to form a finished stud. Fig. S shows a stud having a body 37 of cementitious material, from whichy projects channels 38 embedded in the ends of. thestuds. Also embedded in the body and projecting laterally therefrom are prongs 39 for attachingv the metal lath in place.

In Fig. 3, floor slabs are indicated'. by 40 and 4l. Suspended from floor slab 40 is a ceiling 42. A. channel 43 is placed upon the ceiling in alignment with the plane in which the partition is placed, and in registration therewith on the floor slab 4l is a. channel plate 44. This type of construction serves for studs such as are shown in Fig. 5 or 7,`

such a 'stud being indicated generally by 45 in Fig. 3. The metal lath is fastened to the stud 45 and brought up to the ceilingv and downwardly to the floor.

It is obvious that various modifications may be made in the structure without departing from my invention which is defined in the appended claims.

What I claim is:

l. A stud comprising a. metallic channel bar covered by a comparatively soft cementitious body, said bar being provided with bendable attachment prongs supported `thereby projecting through said body.

ton projectingV beyond the ends of said bodyy to provide fingers adapted for 'securing said stud in a building structure.

4. Astrid comprising a metallic skeleton provided with laterally projecting attachment prongs, said skeleton being covered by a ceinentitious body, said prongs and the ends of said skeleton being exposed whereby to provide fingersv adapted for securing said stud in a building structure.

In Witness that I claim the foregoing I have hereunto subscribed my name this 24th day of November 1923.

CORNELIUS COLLINS.
